I recently installed the Chatterer mod, a mod that adds beeps and radio communication to the game. For some reason it just adds to the atmosphere of the game so much. Hearing the Kerbonauts communicating and the beeps and signals of the ship makes space flights feel more realistic and enjoyable. By "useless" i mean mods that don't necessarily change any mechanics of the game, but rather slightly modify it. What are some other "useless" mods that you know of? I'm all ears! -Spragoo
